Taylor Swift joined Nelly onstage at Karlie Kloss’ birthday party in the Hamptons on Saturday night — and the pair performed a duet to Nelly’s hit single “Dilemma.”

Taylor Swift & Nelly Sing A Duet At Karlie Kloss’ Birthday Bash

Nelly invited Swift to the stage, telling her, “I know you got this. Let’s go!” Suddenly, the familiar beat to the rapper’s 2002 hit “Dilemma” began to play, Swift was handed the mic and the audience exploded in cheers.

Swift danced around Nelly on the stage, singing Kelly Rowlands verses of the song throughout their duet.

The pair even performed a duet last year, when the rapper joined Swift onstage at the St. Louis, Missouri, concert during her 1989 World Tour. Nelly and Swift sang the rapper’s smash hit “Hot in Here” with some help from HAIM.

“She’s just a dope person,” Nelly told Rolling Stone following their Missouri performance. “She ain’t got no ill wills or nothing like that, and that’s kind of hard when you come from where we come from. You rarely come across those type of people. It’s kind of like, Taylor Swift and my granny. Who doesn’t love both of those people?”

Kloss turned 24 last Wednesday and Swift posted a selfie and special birthday message to her on her birthday.

“I LOVE YOU KARLIE,” Swift wrote on Instagram. “You’re such an exquisite person, always trying to make things better for others. Every day I’m inspired by how giving, loving, and thoughtful you are. Happy 24th Birthday!!! @karliekloss.”
